Asia: Endemic to the Amur River system. Two morphs, brown and gray, represent the species in the Amur River basin. Occurrence in the Sea of Japan (Ref. 11102) needs confirmation. International trade restricted (CITES II, since 1.4.98; CMS Appendix II).

Biology     Glossary (e.g. epibenthic)

Adults occur in stretches of rivers with sandy or stony bottom. Feed on benthic organisms. Highly prized fish (Ref. 41072).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00257 (0.00159 - 0.00417), b=3.27 (3.14 - 3.40), based on LWR estimates for species & Genus-BS (Ref. 93245).
Trophic Level (Ref. 69278):  4.4   ±0.25 se; Based on food items.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (tm=8-14; Fec=29,000).
Vulnerability (Ref. 59153):  Very high vulnerability (85 of 100) .
Price category (Ref. 80766):   Unknown.
